Cure for oneitis
You have oneitis. I'm not insulting you, I've had it a lot of times in my life. It's a dreadful disease set on by the corrupt culture programming of the male species.
There is only ONE cure for oneitis, despite that others say there are more cures. There aren't.
The cure? Date more women, or as Rollo Tomassi would say, spin more plates. That is the only way to get rid of oneitis.
Dating more puts you on another playing field. You realize that:
1. There are more fish in the seas.
2. Some of these fish really like you.
3. Your old oneitis gal may have been nice, but she's not the end-all.
4. It builds your confidence. Heck, just the action of asking one out -- even with a rejection -- is liberating. I asked out a gal last night and the date isn't going to happen for awhile (after New Year's, I'm traveling), but her enthusiasm and smile gave me a jolt of confidence. (Yeah, her accepting the date helped, too.)
5. Dating a variety of women allows you to put your own checks and balances out there. Instead of focusing on one, you focus on many and find out what you like and dislike in a woman. It's like shopping: Do you want to go to a grocery store with one brand of milk, only one type of meat, only one type of cereal, etc.? No, you need choices.
... I could go on, but I'd highly suggest you do a search for Rollo Tomassi's posts on oneitis and the "sniper mentality" vs. the "machine gun mentality" ... it's quite good and better than anything I've written here.
Good luck! I've been there bro, it's not fun. But I was there without the aid of sosuave.com. We're here to save the day!
